Definitions

  • the invention relates to a system, and a method of utilizing that system, to attach natural or artificial hair extensions, hair pieces or other hair enhancers to natural hair growing on an individual's head to lengthen or thicken the appearance of the hair.
  • scalp hair also medically designated as capillus or capilli.
  • the simplest approach is to apply a wig or add hair pieces such as pony tails, braids or wefts.
  • a permanent procedure is the use of hair plugs which are surgically implanted.
  • a temporary method suitable for longer periods of time is to sew or weave strands of natural hair or synthetic hair replacements into normal hair growing on the scalp.
  • hair extensions may be adhesively secured to the scalp or hair growing from the scalp.
  • a still further method is to use small clamps or clips for the attachment of strands or bundles of hair, referred to as a hair extensions, to multiplestrands of scalp hair.
  • US Patent 4,934, 387 shows the use of a thermoplastic glue
  • US Patent 5,072,745 discloses use of a hot melt adhesive
  • US Patent 5,575,298 uses a contact adhesive
  • US Patent 5,868,145 uses a liquid latex along with a cyanoacrylate adhesive
  • US Patent 6,405,736 and US Published Applications 2002/0185146, 2001/0035192 and 2001/0037813 each disclose a self adhesive tape for attaching an extension or multiple extensions to the scalp.
  • US Patent 5,107,867 describes the use of a thermosetting adhesive in combination with a heat shrinkable tubing. These techniques require the use of heat and/or solvents to reverse the attachment process.
  • US patent 5,121,761 describes a method of attaching hair extensions which first requires securing anchors to multiple strands of hair attached to the scalp, forming the hair extensions into a single wide hair piece with an upper weave portion an attaching that weave portion to the anchors.
  • US Patent 5,894,846 describes the attachment of hair extensions to strands of knotted, scalp hair using heat shrinkable tubes. The hair is first knotted to form an enlarged portion that is readily trapped in the tubing after heat is applied to cause shrinking of the tubing.
  • US Patent 5,752,530 to Taintinger describes a process for attaching hair extensions to scalp hair which comprises using a clamping tool to temporarily clamp loose strands of a hair extension to gathered strands of hair near the scalp, placing the combined hair extension and scalp hair strands through a threading loop and then pulling that combination through a straight cylindrical sleeve.
  • the hair extension and scalp hair are then trapped in the sleeve by crushing the cylindrical sleeve first into a U or V shape, with the bottom of the U or V extending along the length of the cylindrical sleeve (parallel to the hair strands), to loosely grasp the strands, sliding the sleeve along the strands until it is close to the scalp and then further folding the sleeve over on itself (i.e. folding the sleeve in half longitudinally) thus compressing the U or V shape, trapping the hair strands within the crushed, folded sleeve.
  • Special pliers which includes a U or V shaped groove in one face and a matching anvil shaped extension in the other face of the plier jaws are used to form the tube into the desired hollow U or V configuration with the hair within the reshaped hollow cylinder. Another portion of the plier jaws is then used to complete the formation of the folded U or V shaped cylinder. To undo the process (remove the hair extension) the pointed tips of the pliers are used to unfold the folded U or V, releasing the compressive forces on the scalp hair and hair extension.
  • Other tools and methods for the attachment of hair extensions are disclosed in DE 200 09 406 4, which is regarded as closest prior art, as we has in US 6 109 274 and GB 2 271 057.
  • the present invention provides a process according to claim 1 and a system according to claim 7.
  • hair extensions are applied to natural hair growing on the scalp of an individual using flared cylindrical tubes, a threading hook and a specially design crimping tool. Because the crimped tube readily receives a removal tool designed to fit within the crimped tube, the extension can be readily removed at any time.

  • Natural, modified natural or synthetic water soluble or swellable polymers such as polysaccharides, alginates, gums, proteins, cellulose ethers, starch derivatives, polyacrylamide, polyvinyl alcohols, polyvinylpyrrolidone, polyacrylic acid, or polyphosphoric acid are preferred.
  • this list is not intended to be all-inclusive and one skilled-in-the-art, based on the teachings herein will recognize that the beneficial results of the invention described herein can be obtained, and the method described can utilize hair extensions with many different binding materials.
  • the color of the strands 32 in the extension 30 are typically selected to match or complement the color of the natural hair 38 growing from the scalp 28 of the individual receiving the hair extension.
  • Figure 20 shows an example of a single hair extension 30 after attachment to the head of an individual using the methods and devices incorporating features of the invention.
  • a typical hair extension for use in the flared tube of the invention range has an insertion end diameter D E ranging from about 0.030 to about 0.070 inches, with the binding material covering about 0.2 to about 0.5 inches of the end of the extension, and will comprise from about 50 to about 250 strands of hair or fiber, the size of the bundle being chosen based on the dimensions of the flared tube selected. However smaller or larger bundles can be used within the invention disclosed
  • flared tubes 40 shown in figures 1 and 2, and in Figures 3-9, 18 and 19 in various embodiments and stages of the extension attachment procedure, are used to secure multiple hair extensions 30 to scalp hair 38.
  • the preferred flared tubes 40 are thin walled cylindrical tubes that have at least one flared end 42. The flared end aids in threading the tube and inserting the attachment end 36 of the hair extension. The flare also functions to hold the tube slightly open, as shown in Figure 4, so that the sharpened edge of a removal tool can be inserted as part of a removal process.
  • These tubes 40 are preferable formed of malleable copper, aluminum or other readily bendable but not brittle metals or alloys, and are colored to match or complement the color of the hair extension 30 and/or the scalp hair 38 of the individual.
  • Figures 16-18 show an embodiment of a threading tool 50 which may be used to thread scalp hair 38 through the lumen 44 of the flared tube 40. It comprises an elongated shaft 52, the diameter of which is selected to readily receive the different diameter flared tubes without being too tight or too loose for easy manipulation, with a first end having a hooked portion 54 for grabbing strands of hair. It may also include a keeper 56 that aids in holding the strands of hair in the hooked portion 54 as the strands of hair are pulled through the flared tune 40.
  • the keeper 56 in the embodiment shown, is hinged so it is free to swing from an open position, as shown in Fig 16, to a closed position as shown in Fig 17.
  • a larger diameter handle 58 is located on the other end of the shaft for grasping the threading tool 50 and to prevent the flared tube 40 placed on the shaft 52 of the threading tool 50 from falling off the second end.
  • the crimping tool 60 is a plier-like device having an upper jaw 62 and a lower jaw 64 for grasping and crushing the central portion of the flared tube 40 by applying gripping pressure to the handles 69.
  • the upper jaw 62 has a ridge 66 extending across the jaw 62 surface and a the lower jaw 64 has a matching groove 68 extending across the lower jaw 64 surface, sized to receive the ridge 66 on the first jaw 62.

As indicated above, the presence of the flared end provides a space between the inner walls of the tube at its flared ends after crushing to receive the pointed extensions 72. By applying gripping pressure to the handles 74 of the releasing tool 70, the crushed tube can be expanded.
  • the pointed extensions 72 comprise rods cut on a diagonal to create a sharp end for insertion in the ends of the crushed tube as shown in Figure 21.
  • one or both of the extensions 72 can have a pointed end 76 more centrally located.
  • one of the extensions 72 may have a pointed end 76 while the second extension 72 may have a flat surface, or an indented surface 78 complementary to the pointed end 76 on the other extension 72 to receive one end of the crushed tube while the pointed end is inserted in the flared end 42 of the crushed tube 40.
  • a preferred procedure to apply a hair extension 30 to scalp hair 38 using an attachment system incorporating features of the invention comprises the following steps:
  • One or more flared tubes of the desired size and color are threaded on to the threading tool 40 with the flared end 42 towards the handle 58.
  • a flattened bundle of scalp hair 38 preferably about the width of the internal diameter of the tube, is captured in the hook portion 54 of the threading tool 40 (Fig 18).
  • a flared tube is then slid up the threading tool 40 toward the scalp 28, preferably to within 1 ⁇ 4 inch of the scalp, and the scalp hair 38 bundle is released from the threading tool 40 leaving the scalp hair 38 extending from the flared end 42 of the tube 40 (Fig 19).
  • the flared tube 40 is then placed between the flat portions 63, 65 of the upper and lower jaws 62, 64 of the crushing or crimping tool 60, and pressure is applied to the handles 69 to compress the tube, creating a flattened potion across or along some or all of the tube, as shown in Fig 3, 7, 8 or 9, trapping the scalp hair 38 and insertion portion 36 of the hair extension within the crushed or crimped tube.
  • the tube can be placed in the groove 68 and crimped by the ridge 66
  • the tube can then be further flattened by compressing it between flat, adjacent, parallel portions 63, 65 of the upper and lower jaws 62, 64. In either instance, a flattened tube is produced with a width approximating 1 ⁇ 2 of the original outer diameter of the center portion of the tube.
  • Figure 20 shows the result of such a procedure for application of a single extension.
  • the process is then repeated multiple times until the desired number of hair extensions have been added.
  • the procedure can also be repeated across multiple part-lines on the scalp, or randomly, to create a layered effect and a fuller appearing head of hair.
  • the attached hair extensions may be of different diameters or different colors to provide highlighting and shading to the finished head of hair.
  • one of the sharpened extensions 72 of the releasing tool 70 is inserted into the slightly open but crushed flared end 42 of the tube, the second extension 72 is then inserted in or placed against the other end of the tube and compressive forces are applied to handles 74 of the releasing tool 70, causing the crushed tube to expand.
  • the tube can then be slid down the scalp hair bundle away from the scalp, to remove the flared tube and hair extension from the bundle of scalp hair. This process may be aided by applying some heat to the tube and rotating it during the process.
  • Figure 23 shows a wide hair extension 80 which may be comprise multiple hair extensions 30 attached to a mounting band 82.
  • the wide hair extension 80 can comprise numerous strands of hair in a flat array attached to the mounted band 82.
  • the attachment band 82 may be a separate piece of material or may be formed by weaving or braiding the upper end of hair strands 84 into a structure suitable to hold the wide hair extension in a configuration suitable for mounting to an individual's head.
  • Multiple flared tubes 40 are attached to the band by gluing, sewing, etc.
  • the wide hair extension 80 typically has a width of from about 1 ⁇ 2 inch to 6 inches but wider or narrower extensions 80 may be used.
  • a still further embodiment utilizes the extension attachment system for applying wigs or hairpieces 90.
  • a preferred hairpiece would include apertures 96 for pulling strands of scalp hair 38 there through.
  • these apertures 96 are spaces in the central portion of the hair piece 90 which consists of an open mesh, or woven structure formed from the strands or hair or fiber 92 used to construct the hair piece 90.
